DETAILED DESCRIPTION

The disclosed subject matter is described below with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems) and computer program products according to embodiments of the subject matter. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable medium that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable medium produce an article of manufacture including instruction means which implement the function/act specified in the flowchart and/or block diagram block or blocks.

The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide processes for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks.

One technical problem dealt with by the disclosed subject matter is providing a human participant to participate in a social dance without having a partner in the same physical location. In some exemplary embodiments, two people at remote locations would like to dance with each other. Additionally or alternatively, a person would like to perform social dancing activity with a virtual partner.

Social dance activity is based on tactile feedback between the participants, and in many cases is indifferent to visual and auditory cues from the dance partners. Social dancers, depending on the dance, usually make contact hand-to-hand, chest-to-chest, and hand-to-back during the dance routine. Some dancers may even close their eyes when performing a social dance, and focus on the non-visual cues that their dance partner provides.

Another technical problem is to enable plurality of users to participate in a virtual party, such as a ballroom dance.

Yet another technical problem is to allow users to perform any co-operative physical activity, such as but not limited to a martial art exercise, social dance routine, or the like, without being located in the same physical location.

One technical solution provided by the disclosed subject matter is a system comprising movement registration module used to interpret the movements of the participant and a tactile feedback actuator that is configured to provide tactile feedback to the participant. As social dance is based on tactile feedback, merely being able to see a representation of one's partner is inadequate—a way to ‘feel’ them is preferable. The tactile feedback may provide such feedback that simulates the feedback of a dancing partner.

The tactile feedback may be provided based on a response of a dance partner to the participant's movements or dance routines. For clarity, the disclosed subject matter refers to the participant as a male while the dance partner is referred to as a female. However, the disclosed subject matter is not limited in such a way. Furthermore, the disclosed subject matter may be used for social dance routines involving more than two participants, such as square dance, Rueda, or the like.

In some exemplary embodiments, the dance partner may be a virtual dance partner whose actions may be determined by a computer. In some exemplary embodiments, a dancing logic module may calculate the movements of a simulated partner of given skill and style and simulates the tactile feedback accordingly. Additionally or alternatively, the dance partner may be a real dance partner that is in a remote location. The remote dancing partner may act in response to the participant's movements and based upon her responses, tactile feedback may be provided to the participant, such as reflecting the dance partner's movements. In some exemplary embodiments, the tactile feedback may represent the movement of the partner.

In some exemplary embodiments, the participant may be provided with visual and/or audio-based feedback. In some exemplary embodiments, visual feedback may include a graphical display of the dance partner. In some exemplary embodiments, the dance partner may be filmed in real-time and his or her image may be provided. In some exemplary embodiments, an avatar, such as a 3D avatar of the partner may be displayed. In some exemplary embodiments, such as in case the partner is virtual, the avatar may be generated based on computations by the dancing logic module. In some exemplary embodiments, the avatar may be structured based upon the body structure of the partner.

In some exemplary embodiments, the graphical display may further include the participant himself. The image of the participant can be real, such as captured by camera. Additionally or alternatively, the image may be enhanced to look as either dancer pleases.

In some exemplary embodiments, the graphical display may be provided using a display such as a television screen or projector. Additionally or alternatively, the graphical display may be provided in an Augmented Reality (AR) manner, such as Augmented Reality glasses. Augmented Reality devices may be used to increase the participant's feeling that he is dancing with a dance partner, such as by displaying in augmented reality the dance partner in his arms.

In some exemplary embodiments, a dance party with many people (e.g. a ballroom) can be simulated. In some exemplary embodiments, on every participant's side augmented reality devices which simulates the party room may be used. In some exemplary embodiments, anybody could be invited to join the dance party, so as to provide for a virtual dance party based on actual human interaction. In some exemplary embodiments, a simulated ballroom may be computed in which some dancers are humans and some are AI-based.

In some exemplary embodiments, a social dance between two real partners may be presented as part of a larger party that includes virtual dancers. Though only two people are dancing the disclosed subject matter may making it feel like both dancers are part of a larger party.

In some exemplary embodiments, a participant may switch a dance partner from time to time. In some exemplary embodiments, the participant may switch between real and virtual partners.

In some exemplary embodiments, the movement registration module may include a motion sensing input device. The motion sensing input device may be, for example, a remote sensor, such as a video camera, a Kinect™-like system which is based on remotely sensing user movement using radar, sound or the like. Additionally or alternatively, the motion sensing input device may be a body-worn device, such as a glove or body-worn outfit that is capable of sensing, such as using accelerometer, optical sensor, depth sensors, and other electronic means known in the art to sense movement of a person wearing the device. It will be noted that in the present disclosure “body-worn” may refer to an item that is worn by a participant, held or carried by him, or otherwise coupled to the body of the participant.

In some exemplary embodiments, the same body-worn device used for motion sensing may include the tactile feedback actuator.

In some exemplary embodiments, the tactile feedback actuator may be located on the participant's body so as to supply tactile feedback on the participant's hand, chest, back, hips, or the like.

In some exemplary embodiments, a body-worn device may be limited, in comparison to external devices, as it may be required to give the feeling of outside force a mobile device but it may not actually apply outside force. In some exemplary embodiments, an external device may limit the movements of the participant and therefore it may be desired to avoid the use thereof.

In some exemplary embodiments, the disclosed subject matter may be configured to identify movements and reflect those movements on a dance partner. In some exemplary embodiments, precision of reflection may be desired, such as to allow professional dancers or martial art experts to improve their performance and detect subtle differences. In some exemplary embodiments, it may not be sufficient to simply interpret a gesture to comprehend the participant's intent, but rather it may be desirable to reflect the movements as is and allow the dance partner interpret the underlying intent on her own.

One technical effect may be enabling a participant to interact with an electronic system by performing social dancing. Another technical effect may be allowing the participant to interact with the system without relying on his sense of sight (e.g., with his eyes closed). Yet another technical effect may be to increase range of social interactions with remote users to include social dancing activities.

Referring now to FIG. 1A showing an illustration of a computerized environment, in accordance with some embodiments of the disclosed subject matter.
